Reacción a "Emissions released since the Paris Agreement have intensified recent heatwaves in Europe"

The study adds a further assessment which highlights the growing body of evidence that there is a close link between the continued rise in global emissions and the intensification of summer heatwaves in Europe between 2021 and 2025. They even provide a quantification: they estimate that the June 2025 heatwave was approximately 0.34 °C warmer across Europe than it would have been without emissions. To achieve this, they use generative artificial intelligence to overcome some of the limitations of extreme event attribution to date. However, there are significant limitations that must be taken into account, such as statistical robustness for small spatial scales (~250 km – which, in practice, are not so small for some extreme events) compared with the regional average (~2,500 km), and the exclusion of land-use or aerosol forcings.

As for the implications, the results indicate that pollution emitted in the last decade alone is already having a direct and measurable impact on the scale of current climate-related disasters. This reinforces existing studies and underlines the unavoidable and urgent need to reduce emissions and even the concentrations of greenhouse gases already present in our atmosphere.
